This example shows a yellow smiley face composed of SVG shapes, with circular eyes, a thick outlined face, and an arc-shaped mouth drawn centered on a 960×500 canvas. The visualization is built using React for component structure and D3’s `arc` generator to compute the mouth path. D3 v5 supplies the arc shape, while React handles rendering the SVG elements, including circles for the face and eyes, a path for the mouth, and a text label. All dimensions and positions are defined as constants in the code.
